SPECIFICATION forming part of Letters Patent No. 447,592, dated March 3, 1891.

Application filed ly 10, 18%| Serial No. 358,244 (No model.)

To all whom it may concern/.-

Be it known that I, CHAUNCEY F. WHIPPLE, a citizen of the United States, residing at Nevinville, in the county of Adams and State of Iowa, have invented certain new and useful Improvements in \Vell-Borin g Machines and I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in well-digging apparatus; and it consists in the construction and arrangement of parts hereinafter described, and definitely pointed out in the claims.

The object of my invention is to provide an apparatus for facilitating; the excavation of wells which will be readily operated with but little labor on the part of the operator. I attain this object by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate corresponding parts in the several views,in which Figure 1 is a side elevation of my apparatus. Fig. 2 is a front elevation. Fig. 3 is a rear view, partly in section, with the elevatoroperating mechanism removed. Fig. 4 is a top plan view, and Fig. 5 is a detail view of the top, partly in section.

In the drawings, A represents a rectangular vertical standard having a pointed shoe on its lower end and a series of adjusting side notches cut therein.

13 represents a supporting and retaining guide having radial arms Z) with curved shoes I) on their ends, constructed to correspond with the contour of the well. These arms are formed in sections, the inner portions being pivoted to the outer portions, and are hinged to a cylindrical collar b fitted around a collar b surrounding the shaft, the collar b being held in place by suitable flanges on the edges of the collar D which latter collar has a rectangular central opening therein, through which the standard passes. By drawing down on these collars the arms are extended and arranged substantially horizontal, forcing the justable curbing.

curved shoes tightly against the walls of the well.

C is a frame in which are mounted a series of friction-rollers c.

D is a large friction-disk on the standard, having a groove in its periphery, in which the edge of the rollers fit. To retain the disk and thereby the frame in position, a tooth B is formed thereon, which engages an indent on aswinging rod B secured to the collar 12 of the arms.

E is a sprocket-wheel mounted on an axle e journaled in the frame beyond the frictiondisk.

F is a drive-chain, to which any suitable power may be applied to operate the several parts.

. On the inner end of the axle is a beveled friction-disk F which engages with the beveled under edge of the disk D and rotates the same.

.Iournaled in a suitable bearing formed in the disk D is a long pendent rod G, carrying near its upper end a pinion g, which engages with a stationary circular rack H on the frame. Sleeved on this rod- G is a beveled pinion I, it being keyed on the rod in a suit able manner to allow it a vertical but not a rotary movement independent of the rod.

J is a bracket fast to the standard and supporting the pinion I. A similar bracket supports a vertically-disposed beveled pinion K, carrying a band-pulley K and meshing with the pinion I.

L represents a platform secured on thelower end of the standard having extensionsl fitted in suitable T-shaped grooves formedin an ad- L is a horizontal screw journaled in the platform and carrying a beveled pinion Z on its inner end meshing with a light pinion on a hand-shaft P. On this screw is placed a block M, having a threaded aperture, and in which is adjustably secured the standard of a, plow or cutter N. By turning the screw the plow is forced radially out or in, as the case may be. The adjustability of the plow permits a variation of its inclination.

Secured by suitable braces to the standard A is an elevator or conveyer 0, consisting of an inclined casing and having a chute or hopper 0 below and extending to one side to a point directly over the platform, on which a suitable bucket I is adapted to be placed. On the lower end of the elevator is formed a curved scraper 0', which carries the excavated earth up to a point where the buckets 0 gather the same and elevate it. 011 the upper roll of the conveyor is a pulley or sprocket-wheel over which passes a belt or chain, which also passes over the pulley K.

To retain the arms (I in their extended position and support the rectangular frame, I secure to the inside of the inn er collar a swinging rack B having teeth in its side which engage with a tongue 13 on the inside of the large disk D, as shown in Fig. 5. The end of this rack has a handle I3 thereon for operating the same. To lower the plow the lever Q, located on the side of the standard and having a suitable pin on its upper end engaging the grooves or apertures in the standard, is moved sidewise, disengaging the pin and permitting the shoe on the standard to again penetrate the earth, bringing the plow into the same, where it is again ready for work.

In operation my apparatus is manipulated as follows: The apparatus is lowered into position, the guide secured in place, and the plow allowed to enter the ground. Power is then transmitted through the drivechain, actuating the large friction-disk, which turns the standard carrying the plow, which is placed at an incline, breaks the earth and turns it in toward the conveyer, from which it is discharged into a suitable bucket, which is elevated in the usual manner. As the plow moves in a circle the operator forces it out until it loosens the earth to the proper point, it is then drawn back, an d, owing to the inclination, forces the earth toward the center to the elevator or conveyer. The apparatus will now be practically suspended by the guide-arms on the lower part of the elevator, the scraper being employed to collect and cut away the earth from around the shoe. The plow is now lowered by releasing the standard and allowing the same to again make the cut. The well is curbed as the excavation progresses.

I am aware that many minor changes in the construction and arrangement of the parts of my device can be made and substituted for those herein shown' and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl 1. In a well-digging apparatus, the combination,with the vertically-movable standard, of a platform located near the end of the same, a radially-movable plow on the platform, a supporting-frame, and gearing in the frame for rotating the standard and plow, substantially as described.

2. The combination, with the standard, of a supporting-guide consisting of radial arms carrying curved shoes on their ends, a collar to which said arms are pivoted, whereby the downward movement of the collar forces the arms out, substantially as described.

The combination, with a standard, of a supporting guide frame having extensible arms, a friction-disk, friction-wheels in the the frame engaging the disk, means for rotating the standard, and an excavating device on the standard, substantially as described.

4. The combination, with the standard and its actuating means, of an elevator, a pendent driving-shaft connecting the actuating means, a sliding gear on the shaft, and connecting' means between the gear and elevator, substantially as described.

5. The combination, with the standard, of the supporting-guide having jointed arms and curved shoes on the arms, a collar to which the inner ends of the arms are hinged, and a catch on the supporting-frame for engaging the collar and retaining the arms in their distended position, substantially as described.

6. The combination, with the supporting guide-frame, of the large friction disk, the grooved wheel, extensible arms supporting the disk, and the standard carrying the excavator, passing through the disk, substantially as described.

7. The combination, with a standard, of a frame, a pivoted screw in the frame, a plow having an apertured connection with the screw, and a hand-wheel for actuating the screw to move the plow, substantially as described.

S. The combination, with the standard, of a radially-movable plow, an elevator, and means for rotating the standard, substantially as described.

In testimony whereof Iatiix my signature in presence of two witnesses.
